Embodiment 1

[0024] Example 1 Indoor Toxicity Measurement

[0025] 1. Drug preparation

[0026] The selected medicaments are: 92.5% dipropacyclopyrene technical product, 3% piperrine enamide aqueous emulsion. When making the compound insecticidal composition, the mass ratios of piperine and dipropacyclopyrene are respectively selected as 1:1, 2:1, 4:1, 10:1, 20:1, 40:1, and 80 :1, 100:1. The single agent and compound insecticidal composition are diluted with acetone to be 10000mg / L mother liquor for later use, and each single agent and each group of compounded mixtures are respectively diluted to 5-7 concentration gradients.

[0027] 2. Processing method

[0028] Toxic effects of insecticides on aphids were determined by insect dipping method. Pick fresh young apple shoots with aphids from the field, remove excess aphids, keep healthy wingless adult aphids with basically the same size, immerse them in the liquid medicine for 5 seconds, take them out and dry them, and put them in a filt...

Embodiment 2

[0045] Example 2: Field control effect of the piperpinenamide·dipropyridine insecticidal composition on the apple yellow aphid

[0046] 1. Processing conditions

[0047] The treatment object is yellow aphid, and the test crop is apple tree, and the variety is red Fuji.

[0048]The treatment was carried out at the treatment site of the Yantai Academy of Agricultural Sciences in Shandong Province, where the apple yellow aphid occurred generally and evenly over the years; during the treatment period, the apple growth period was the fruit expansion period, and the cultivation conditions of all treatment plots (soil type, fertilization, growth stage, Plant row spacing, etc.) and plant growth are uniform, and consistent with the local cultivation measures.

[0049] 2. Processing flow

[0050] The treatment agent is a 5% piperamine-diproppyridine insecticidal composition compounded according to 4:1 by the Institute of Plant Protection, Yantai Academy of Agricultural Sciences, Shand...

Embodiment 3

[0064] Example 3: Field control effect of the piperpinenamide·dipropyridine insecticidal composition on the green leafhopper of tea

[0065] 1. Processing conditions

[0066] The object of treatment is the tea leafhopper, and the treatment is carried out in Longquan Town, Mouping District, Yantai City, Shandong Province. The tested tea variety is Pingyang Tezao, and the occurrence of the green leafhopper is generally uniform in the tested tea gardens. The cultivation conditions (soil type, fertilization, growth stage, row spacing, etc.) and plant growth of all treatment plots were uniform and consistent with local cultivation measures.

[0067] 2. Processing flow

[0068] The treatment medicament is the 22% piperrine · dipropacyclopyrene insecticidal composition compounded according to 10: 1 by the Plant Protection Institute of Yantai Academy of Agricultural Sciences, Shandong Province (containing 20% ​​piperine and 2% dipropane Pyrethrin), the contrast agent is 5% dipropacy...

Abstract

The invention provides a composition for preventing and treating piercing-sucking mouthpart pests, a pesticide and application, and belongs to the technical field of pest control. The composition is prepared from the following components: capsaicin alkenyl amide and afidopyropen. In the invention, the capsaicin alkenyl amide, as known as capsaicine, has contact action and stomach toxicity action on pests; the afidopyropen interferes with the function of an insect string tone device, so that insects lose induction to the environment, cannot eat and lose water, and finally die due to hunger. Theaction mechanisms of the capsaicin alkenyl amide and the afidopyropen are different, the pesticide resistance is not easy to generate after compounding, the service life of the pesticide is prolonged, the use cost is reduced, and the pollution to the environment is reduced. The capsaicin alkenyl amide and the afidopyropen in the composition disclosed by the invention have an obvious synergistic effect. The composition provided by the invention has a better control effect than a single agent in controlling aphids, empoasca flavescens and bemisia tabaci, and the use amount of the single agent is reduced.

Description

technical field [0001] The invention relates to the technical field of pest control, in particular to a composition, an insecticide and an application for preventing and controlling piercing-sucking mouthparts pests. Background technique [0002] Piercing-sucking mouthparts pests commonly occur in major crop producing areas in my country, mainly including aphids, leafhoppers, thrips, mirid bugs, planthoppers and other pests, which suck plant juice, causing damage to plant leaves, fruit Stop growing, bring huge economic loss to crop production. At present, its control is mainly controlled by chemical pesticides, and the commonly used pesticides are mainly imidacloprid, thiamethoxam, buprofezin and chlorpyrifos. With the long-term repeated use of pesticides, pests are becoming more and more resistant to conventional insecticides, and the amount of pesticides is also increasing. Contents of the invention [0003] The object of the present invention is to provide a compositio...
